HAMME RQ WITH SHIN GLE -CUTTING ATTACHMENT.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed April 22, 1908. Serial No. 428,625.

To all whom it may concern:

Be it known that we, BERNARD M. WELLS and FREDERICK W. Snnrsrnnj citizens of the United States, residing in Paterson, Passaic county, New Jersey, have invented a certain new and useful Improvement in Hammers with Shingle-Cutting Attachments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification The object of this invention is to provide a knife attachment for hammers and similar implements which shall be simple and in pensive in construction and capable of being readily and securely attached to various sizes and shapes of hammers; when the knife is attached to the hammer, it forms an implement which may be used interchangeably either as a hammer or as a means ior trimming shingles and other similar purposes.

The inventmn will be found fully illus trated in the accompanying drawings, wherein,

Figure l is a side view of a hammer with the knife attachment in place thereon; Fig. 2 is a rear view oi what is shown in Fig. 1; Fig. 3 is a perspective view of the attachmerit; and, Fig. 4. is a sectional view of the attachment and of a fragment of the hammer, on line a;-;r, Fig. 1.

In the drawings, a designates the head of a hammer, having the usual nail-driving portion 5 and the claw-portion c, and d is the handle of the hammer.

e designates the kni'fc-attachment. This consists of a curved lat blade f, having its convex edge 9 sharp, and the laterally extending attaching members it and i preferably formed as integral parts of the blade. The member h is a strap-shaped part extending downwardly from the forward end of the blade f, then bent laterally in a right angle, then bent upwardly in a right angle, and then bent laterally again in a right angle, and then bent downwardly in a right angle. There is is thus formed a clamp 3' one side 7c of which is not only spaced from the other side Z so as to receive the head of the hammer, but is also spaced or oifset with relation to the blade 9.

The member 1' is substantially a laterally extending strap shaped loop the opening m of which is sulliciently large to receive one of the claws of the hammer. The loop is of such formation (see Figs. 2 and 3) as to bring the opening thereof in oilset relation to the blade 9.

In the side Z of the clamp j is arranged a set screw n which preferably has a sharp point 0 (see Fig. 4).

In assembling the knife attachment and the hammer, the loop 6 is slipped over one of the claws of the hammer and the clamp made to receive the head of the hammer in the manner shown in Figs. 1 and 2, whereupon the set screw is manipulated to secure the clamp to the hammer-head. If desired, the user may dent the side of the hammerhead, as with a nail-set, so that the oint 0 of the screw may engage in such out to afford a better grip for the screw on the hammer-dread.

The implement thus produced may be used either as a hammer for driving nails or, by means of its claws, for drawing them, or it may be used for trimming shingles and the like by a chopping stroke; the oll'sot relation of the blade with respect to the hammerhead aifords clearance for the shavings produced.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:

1. The combination, with a hammer, of a cutting attachment therefor comprising a blade disposed substantially side by side with the head of the hammer and means substantially at the ends of said blade for securing the attachment to the hammer, substantially as described.

2. The combination, with a hammer, of a cutting attachment therefor comprising a blade disposed substantially sidc by side with the head of the hammer; and attaching means comprising a laterally projecting open clamp adapted to receive a part of the hammer, and a set-screw arranged in the clamp and adapted to bind against the hammer, substantially as described.

3. The combination, with a hammer, of a cutting attachment therefor comprising a blade disposed substantially side by side with the head of the hammer-and moans, formed rigid with respect to the blade, for securing the attachment to the hammer, substantially as described.

1. As an article of manufacture, a cutting attachment for hammers and the like tools consisting of a blade, and attaching means We have hereunto set our hands this 18th day carried by the blade and comprising a loopof Apr'l, 1908.

shaped member adapted to receive a part of BERNARD M NELLS the tool, an open clamp adapted also to re- Y ceive a art of the tool and a screw in the FREDERICK SIMISTER' clamp a apted to bind against the tool, sub Witnesses: stantially as described. JpHN WV. STEWARD,
